摘　　要：为了研究截顶M型药型罩的结构对聚能射流的性能影响,利用ANSYS/LS-DYNA对9组聚能装药结构进行数值模拟分析。通过改变药型罩截顶宽度和V型开口宽度,分析聚能射流的速度、长度以及连续性变化。结果表明,在9组不同的方案中,射流的速度随着药型罩截顶宽度和V型开口宽度的增加呈现先增加后减小的趋势。当截顶宽度为1.2 cm,V型开口宽度为0.4 cm时,射流的形态更好,射流头部速度最大,为6007 m/s。In order to study the influence of the truncated M-shaped charge cover on the shaped charge jet,ANSYS/LS-DYNA was used to simulate and analyze the performance of 9 groups of shaped charge.By changing the width of the truncated cap and the width of the V-shaped opening,the velocity,length and continuity of the shaped jet were analyzed.The results show that in the 9 schemes,the velocity of the shaped jet increases first and then decreases with the growing of the truncated width and the V-shaped opening width.When the truncated width is 1.2 cm and the V-shaped opening width is 0.4 cm,the shape of the jet is better and the jet head velocity reaches the maximum,6007 m/s.
